Database Abstraction

Hello! I have a question: Do you have any intention to include a feature like database abstraction layer at PHP4? I was thinking to use PHPLib to do this, but I have found some things at their code that I didn't like... Of course that I can write functions or classes just to do that but if we have something implemented directly in PHP4 it will be easier and the most important thing: it's difficult to implement something really generic that can be used with all databases. I think that we need specialists at many DBMS to do the right thing and to have good performance at all of them. I've worked a lot with Oracle but I didn't know the other DBMS suficiently to do a really good work. The databases are the heart of a site and if you loose performance doing dumby functions, it can be critical... If there is an interest in implementing that, I would like to colaborate. Thanks, Andre. PS: Sorry about any English mistakes... My portuguese is better! :-))
